Claims. (01. 104-40) This invention relates to new and useful improvements in a turntable. Its primary object being to provide a turntable for automobiles, trucks and the like having operating means attached thereto whereby the said turntable may be revolved by the movement of the vehicle there-,-

A further object of the invention is to provide means whereby the turntable may be operated by .0 the driver of the vehicle without leaving his seat thus economizing in time.

With these and other objects in view that may appear while the description proceeds the invention consists in the novel construction and ar- 15 rangement of parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawings and in which Fig. 1 is a plan view of my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a cross section taken through the center of Fig. 1 showing details of the turntable.

Fig. 4 is a side view of the notched T bar.

Fig. 5 is a detail view of the member attached to the truck to engage the notched T bar.

Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views it will be seen the invention comprises turntable longitudinal frame members each having a wheel guard 11 secured thereon to keep the vehicle on the upper surface of the said frame member 10. Frame members 12 are positioned at intervals between the said longitudinal members 10 and the whole frame rigidly secured together by bolts 13.

The turntable structure is pivoted on a stationary shaft 14 having a large annular flange 15 at the bottom thereof which is bolted to the base supporting structure 16. A loose plate 17 having a central orifice therein is positioned centrally on the said shaft 14 and likewise bolted to the said base structure on the top thereof in corresponding relation to the flange 15, forming additional support for the shaft. A pivot bearing is formed in one of the lateral frame members 12 and bearing plates 18 secured on the top and bottom thereof through which the shaft extends. On the upper end of the said shaft is a cable drum 19 which is secured thereto by a key 20 to prevent rotation of the same.

On the upper surface of the base structure 16 is an annular track 21 and on the lower surface of the turntable structure is a corresponding annular 55 track 22. Positioned therebetween are a plurality of rollers 23 rotatably mounted on radial shafts 24 which are secured to a central annular ring 25 loosely mounted on the shaft 14.

A cable 26 is wrapped around the drum l9 and extends to each end of the turntable and is passed through pulley blocks 2'7 and back toward the center where each end is securely fastened to a T bar 28. The said T bar is formed in a plurality of sections and hinged together by the hinge plate members 29, and the center rib provided with a plurality of notches 30 spaced at regular intervals therein. A longitudinal support member 31 is secured across the tops of the frame members 12 andthe said T bar is slidably mounts ed thereon between guide members 32 which are secured to the said support member 31.

An attachment is provided for the vehicle to be turned on the turntable and-comprises a member 33 to be hinged to the front axle of the said t vehicle. A cross member 34 is designed to engage .75 i

the notches 30 in the T bar. A lug 35 is provided thereon and a rope or cable 36 attached thereto whereby the member may be lowered or raised to engage or disengage the T bar from the vehicle drivers seat.

In operation the vehicle is driven onto the turntable to almost balancing point then the member 33 is lowered into engagement with a notch in the T bar. A forward movement of the vehicle is transferred to the cable and the pull on the drum will cause the turntable to rotate. A sufficient length of cable is provided to allow a half turn only, so that the T bar is in a position to operate the device again after each half turn.

It is believed that the construction and advantages of the structure shown may be apparent from the foregoing paragraphs taken in conjunction with the accompanying drawings without further detailed description.

While the preferred embodiment of the struc- A ture has been disclosed it is understood that minor changes in the details of construction, combination and arrangement of co-operating parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

I claim:

1. In a turntable of the type described, a rotatably mounted turntable structure, a stationary base structure, a stationary pivot shaft secured thereto having a drum keyed on the upper end thereof means connected to said drum and means carried by a vehicle on said turntable structure to actuate said first mentioned means and set said turntable structure in motion by the motion of said vehicle.

2. In a turntable of the type described, a stationary pivot shaft, a turntable structure rotatably mounted thereon, a stationary base structure supporting the same, a stationary cable drum mounted on the upper end of said pivot shaft, a cable connected thereto, pulley blocks at each endof said turntable through which the said cable is passed, a T bar slidably mounted in guides on the deck of the said turntable having a plurality of notches in the upward extending central web thereof, said cable being fastened to each end of said T bar and means engaging said notches from a vehicle on said turntable actuating the same to rotate the turntable by the motion of the said vehicle.

3. In a turntable of the type described, a stationary pivot shaft, a turntable structure rotatably mounted thereon, a stationary base structure supporting the same, a stationary cable drum mounted on the upper end of said pivot shaft, a cable connected thereto, pulley blocks at each end of said turntable through which the said cable is passed, a T bar slidably mounted in guides on the deck of the said turntable having a plurality of notches in the upward extending central web thereof, said T bar being formed of a plurality of like members pivotally connected to each other by pivot pins and side plates, said cable being fastened to each end of said Tbar and means engaging said notches from a vehicle on said turntable actuating the same to rotate the turntable by the motion of the said vehicle.

4. In a turntable of the type described, a stationary pivot shaft, a turntable structure rotatably mounted thereon, a stationary base structure supporting the same, an annular flange on the base of said pivot shaft bolted to the bottom of said base structure, an annular plate with a central orifice therein bolted on the upper side of the base structure supporting said shaft, an annular track on the top of the base structure, a similar annular track on the bottom of the turntable structure and rollers positioned therebetween, a shaft guide bearing in the said turntable structure, a stationary cable drum mounted on the upper end of said pivot shaft, a cable connected thereto, pulley blocks at each end of said turntable through which the said cable is passed, a ,T bar slidably mounted on the deck of said turntable having a series of notches therein,

said cable endsbeing fastened to each end of said T bar and means engaging said notches from a vehicle on said turntable actuating the same to rotate the turntable by the motion of the said vehicle.

5. In a turntable of the type described, a stationary pivot shaft, a turntable structure rotatably mounted thereon, a stationary base structure supporting the same, a stationary cable drum mounted on the upper end of said pivot shaft, a cable connected thereto, pulley blocks at each end of said turntable through which the said cable is passed, a T bar slidably mounted in guides on the deck of the said turntable having a plurality of notches in the upward extending central web thereof, said cable ends being fastened to each end of said T bar, a hinged member to be secured to the vehicle using the turntable and having 'a cross member therein to engage said notches in the said T bar, and a rope attached thereto whereby the member may be lowered or raised by the vehicle driver, substantially as set forth.
